EXPLANATION OF THE AC SYMBOLS

Each timing symbol has five characters. The first character is always

‘t’ (= time). The other characters, depending on their positions,

indicate the name of a signal or the logical status of that signal.

The designations are:

C – Clock

D – Input data

H – Logic level high

L – Logic level low

Q – Output data

T – Time

V – Valid

X – No longer a valid logic level

Z – Float
